In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

In this nutrition activity (page 16 of PDF), learners document their individual eating habits and learn whether their eating patterns meet their needs.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.
